DTC B0137/71 Short to GND in Front Pretensioner Squib LH Circuit
DESCRIPTION
The front pretensioner squib LH circuit consists of the center airbag sensor assembly and the front seat outer belt assembly LH.
This circuit instructs the SRS to deploy when deployment conditions are met.
DTC B0137/71 is recorded when a short to ground is detected in the front pretensioner squib LH circuit.

INSPECTION PROCEDURE
HINT:
1 CHECK FRONT SEAT OUTER BELT ASSEMBLY LH (FRONT PRETENSIONER SQUIB LH)

CAUTION: Never connect a tester to the front seat outer belt assembly LH (front pretensioner squib LH) for measurement, as this may lead to a serious injury due to airbag deployment.
NOTICE: Do not forcibly insert the SST into the terminals of the connector when connecting.
Insert the SST straight into the terminals of the connector.
SST 09843-18060
OK: DTC B0137/71 is not output.
HINT: Codes other than DTC B0137/71 may be output at this time, but they are not related to this check.

DESCRIPTION
The front airbag sensor LH circuit consists of the center airbag sensor
assembly and front airbag sensor
LH.
If the center airbag sensor assembly receives signals from the front airbag
sensor LH, it judges whether or
not ...
Read vin (vehicle identification number)
(a) The VIN reading process is shown in the flowchart
below. Reading the VIN stored in the ECM is
necessary when comparing it to the VIN provided
with the vehicle.
(b) Read the VIN using the intelligent tester.
(c) Check the vehicle's VIN.
(d) Connect the intelligent tester to the DLC3.
